Safety NotesThe installation and assembly of electrical equipment should only be performed by authorized personnel.The product should only be used for the intended application. Unauthorized modifications are prohibited! The product must not be used in relation with any equipment that in case of a failure may threaten, directly or indirectly, human health or life or result in danger to human beings, animals or assets. Ensure all power is disconnected before installing. Do not connect to live/operating equipment.Please comply with • Local laws, health & safety regulations, technical standards and regulations • Condition of the device at the time of installation, to ensure safe installation • This data sheet and installation manual

RemarksAll gas sensors are subject to drift caused by components, resulting in regular re-calibration or replacement units. However the dual channel technology integrates automatic self-calibration technology vs common used ABC-Logic sensors. Dual channel self-calibration technology is ideally suited for applications operating 24/7 hours such as hosiptals or other commerical applications. Manual calibration is not required.
